An AI-assisted tool for efficient prostate cancer diagnosis in low-grade and low-volume cases.

Pathologists diagnose prostate cancer by core needle biopsy. In low-grade and low-volume cases, they look for a few malignant glands out of hundreds within a core. They may miss a few malignant glands, resulting in repeat biopsies or missed therapeutic opportunities.

Acute haemoperitoneum due to small bowel metastases from hepatocellular carcinoma in a long term survivor following previous rupture.

We report a 75-year old patient, presenting with acute abdomen and hemorrhagic shock. He provided history of right hemihepatectomy performed 5 years ago, for ruptured hepatocellular carcinoma on a background of Hepatitis B virus associated liver cirrhosis. A computerized tomography scan showed 5 cm-sized mass exophytic lesion, in the small bowel with haemoperitoneum.

Gland segmentation in prostate histopathological images.

Glandular structural features are important for the tumor pathologist in the assessment of cancer malignancy of prostate tissue slides. The varying shapes and sizes of glands combined with the tedious manual observation task can result in inaccurate assessment. There are also discrepancies and low-level agreement among pathologists, especially in cases of Gleason pattern 3 and pattern 4 prostate adenocarcinoma.

Idiopathic Sclerosing Encapsulating Peritonitis: A Rare Cause of Subacute Intestinal Obstruction.

We present a case of a previously healthy 50-year-old gentleman who had recurrent vomiting and abdominal pain of two-month duration. The patient was subsequently diagnosed with abdominal cocoon on computed tomography. Idiopathic sclerosing encapsulating peritonitis, also known as abdominal cocoon, is a rare cause of small bowel obstruction.

Automated image based prominent nucleoli detection.

Introduction: Nucleolar changes in cancer cells are one of the cytologic features important to the tumor pathologist in cancer assessments of tissue biopsies. However, inter-observer variability and the manual approach to this work hamper the accuracy of the assessment by pathologists. In this paper, we propose a computational method for prominent nucleoli pattern detection.

Fasciola hepatica in a New Zealander traveler.

Fascioliasis is a reemerging zoonosis endemic in many parts of the world. Reports of imported fascioliasis by migrants into nonendemic countries are common, but tourists and business travelers are rarely afflicted. Here, we report a case of a New Zealander traveler who acquired the infection on a business trip.
